- A
A custom organization policy with a CEL condition
Why wrong: Custom constraints are for scenarios not covered by built-in constraints; this one has a built-in constraint.
- B
An IAM policy that only allows creation of Shielded VMs
Why wrong: IAM policies grant permissions, they cannot enforce resource properties.
- C
The built-in constraint constraints/compute.requireShieldedVm
This built-in constraint enforces Shielded VM on all new instances.
- D
A deny policy that denies the permission compute.instances.create unless Shielded VM is enabled
Why wrong: Deny policies cannot check resource properties like Shielded VM.

PCSE Practice Question: Configuring Access Within a Cloud Solution Environment
This PCSE practice question tests your understanding of configuring access within a cloud solution environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security team wants to enforce that all Compute Engine instances in the organization use Shielded VM features (Secure Boot, vTPM, Integrity Monitoring). What should they configure?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The built-in constraint constraints/compute.requireShieldedVm
The organization policy constraint constraints/compute.requireShieldedVm enforces that all new VMs must have Shielded VM enabled. It is a built-in constraint available in the Organization Policy service.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A custom organization policy with a CEL condition
Why it's wrong here
Custom constraints are for scenarios not covered by built-in constraints; this one has a built-in constraint.
- ✗
An IAM policy that only allows creation of Shielded VMs
Why it's wrong here
IAM policies grant permissions, they cannot enforce resource properties.
- ✓
The built-in constraint constraints/compute.requireShieldedVm
Why this is correct
This built-in constraint enforces Shielded VM on all new instances.
Related concept
Standard ACLs match source addresses.
- ✗
A deny policy that denies the permission compute.instances.create unless Shielded VM is enabled
Why it's wrong here
Deny policies cannot check resource properties like Shielded VM.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Trap categories for this question
Scenario analysis trap
Custom constraints are for scenarios not covered by built-in constraints; this one has a built-in constraint.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PCSE ACL questions on filtering logic and placement.
